Removing an Intraconnect Module from an EX4500 Switch

If you need to replace the intraconnect module in an EX4500 switch, use the procedure described in this topic to remove the module.

The intraconnect module is installed horizontally on the rear of the switch.

Note: Operating an EX4500 switch without the intraconnect module is not supported.

Before you begin removing the intraconnect module from an EX4500 switch:

• Ensure that you have taken the necessary precautions to prevent ESD damage (see Prevention of Electrostatic Discharge Damage on EX Series Switches).
• Have instructions and tools for removing the fan tray. See Removing a Fan Tray from an EX4500 Switch.

Ensure that you have the following parts and tools available:

• Electrostatic discharge (ESD) grounding strap
• Phillips screwdriver, number 2
• A replacement intraconnect module (Install the replacement module immediately after removing the module. Operating the switch without this module is not supported.
• An antistatic bag or antistatic mat

Note: You must remove the fan tray from the EX4500 switch before removing the intraconnect module. See Removing a Fan Tray from an EX4500 Switch.

To remove the intraconnect module from the switch (see Figure 1):

1. Halt the switch using the request system halt CLI command:
   
   

   user@switch> request system halt

   Wait until a message appears confirming that switch operation has halted.

2. Disconnect power to the switch by performing one of the following:
   • If the AC power source outlet has a power switch, set it to the OFF (0) position.
   • If the AC power source outlet does not have a power switch, gently pull out the male end of the power cord connected to the power source outlet.
3. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
4. Remove the fan tray from the EX4500 switch. See Removing a Fan Tray from an EX4500 Switch.
5. Loosen the captive screws on the front faceplate of the module using the Phillips screwdriver.
6. Position your fingers under the module as shown in Figure 1 and pull outwards to unseat and eject the module.

   Note: Do not use the captive screws to pull the module out from the chassis. Pull from underneath the front edge of the module.

7. Using both hands, gently slide the intraconnect module halfway out of the chassis.
8. Place one hand under the module to support it and slide it completely out of the chassis.
9. Place the intraconnect module in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Promptly install the replacement intraconnect module. See Installing an Intraconnect Module in an EX4500 Switch.

Note: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of power supply or add a new type of uplink module. It does not apply if you replace these components with the same type of component.
